Lubricating device



Patented Nov. 30, 1943 UNITED STATES PATENT OFFICE LUBRICATING DEVICE Benjamin F. Pease, Jr., Silver Lake, Ohio Application February 20, 1941, Serial No. 379,782

Claims.

This invention relates to improvements in oil cups and similar lubricating devices and to an improved cap for closing the upper ends thereof.

Electric motors and other machinery are now equipped with oil cups in the form of a short tube which is threaded or otherwise secured in a bore leading to the part to be lubricated. Such oil cups are provided with a normally closed, spring operated lid which serves to exclude dust or any objectional matter from the tube. These lids, as ordinarily constructed, have a relatively smooth lower face which cannot be conveniently engaged by an oil spout to open the lid and hold it in an open position while oil is being fed to the tube and it is necessary to use both hands during the oiling operation.

Objects of this invention are to provide an oil cup or tube of simple, economical construction having a lid which is provided on the circumferential edge thereof with means for frictionally engaging the spout of an oil can whereby the oil can can be used with one hand to open the lid and hold it in an open position while oil is fed from the spout to the tube.

The above and other objects and advantages are accomplished by the novel construction, combination, and arrangement of parts illustrated and hereinafter described with reference to the particular adaptation thereof disclosed in the drawing, it being understood that the invention is not confined to the exact form illustrated and that changes and modifications may be made which come within the scope of the claims hereunto appended.

In the drawing,

Figure 1 is a side, elevational view of an oil cup construction in accordance with this invention,

Figure 2 is a side, elevational view of same,

Figure 3 is a vertical, sectional view taken as indicated by the line 3-3 of Figure 2,

Figure 4 is a side, elevational view showing a modified form of the invention,

Figure 5 is a side, elevational view showing another form of the invention.

In the particular adaptation of the invention shown in the drawing, the numeral 6 is employed to denote a tube which is provided with a reduced lower end portion 6a which may be threaded or otherwise secured in a bore leading to a bearing or other part to be lubricated. The tube 6 is provided adjacent the upper end thereof with a lug 'l which projects from the rear side thereof. The lug 1 may be of any suitable construction but as shown is provided with an upper wall la and side walls lb and To which depend therefrom to form an open ended cavity for receiving a spring to be hereinafter described.

The numeral 8 denotes a lid which in Figures 1, 2, 3 and 4 is concavo-convex, with the concave side thereof presented downwardly to engage the free end of the tube 6. The main portion of the lid 8 is larger than the upper end of the tube and the marginal portion thereof projects beyond and overhangs the wall of the tube when the lid 8 is in a closed position. Th downwardly proj ectlng marginal portion of the lid 8 is notched to provide teeth II. In the drawing there is illustrated a lid 3 having a continuous row of teeth II which project downwardly from the forward and lateral sides of the lid. As shown in Figures 1 and 2, the teeth II are inclined rearwardly but it is understood that the teeth may be of any suitable form and arranged in any suitable manner which will accomplish the purposes of the invention.

The lid 8 is provided on the rearwardly presented edge thereof with an extension 9 having depending side walls which embrace the lug I. The side walls lb, 10, and the side walls of the extension 9 are provided with alined bores in which a pin I0 is received to hingedly connect the cap 8 in an operative position on the tube 6. A spring [4 is mounted on the pin l0 and positioned in the cavity l3 with one end thereof engaging the rear edge of the extension 9 to normally hold the lid 8 in a closed position.

In Figure 4 there is shown a concavo-convex lid Bat from which the teeth H are omitted and which can be formed with a sharp, knife-like edge, or with relatively fine serrations or any surface which will accomplish the purposes above set forth.

In Figure 5 there is shown a fiat lid 82) having a flange depending from the outer edge thereof. The flange is provided with depending teeth Ila which serve the same purpose as the teeth H.

In use the spout l2 of an oil can or other device is positioned under the projecting edge of the cap 8. The spout I2 i then moved upwardly to open the lid 8 and oil is forced from the spout l2 into the tube 6. The teeth ll engage the spout l2 to prevent unintentional slipping of the spout from the lid during the oiling operation.

It will thus be seen that the lid can be easily and conveniently operated and oil placed in the tube 6 without using both hands.

Having thus illustrated my invention and described the same in detail, I claim:

1. In an oiling device, a tubular stem, a lid hinged to said stem to close the open end thereof, the free edge portion of said lid projecting beyond said stem and a series of closely spaced depending teeth extending along substantially the entire circumferential edge of said free edge portion.

2. In an oiling device, a tubular stem, a lid hinged thereto to close the open end thereof, the circumferential edge of said lid overhanging said open end, and teeth depending from said circumferential edge throughout substantially the entire free portion thereof.

3. In an oiling device, a tubular stem, a lid hinged to one side thereof, said lid operable to close the open end of said stem, mgtns yieldably holding said lid in a closed position, the circumferential edge of said lid projecting beyond said stem, and teeth depending from substantially the entire free portion of said cir curnferential edge in close spaced relation to said stem.

4. In a lubricating tube, a tubular stem; a lid hinged thereto and projecting beyond the side Walls thereof, and rearwardly inclined teeth depending from substantially the entire free cir cumferential edge of said lid.

5. In a lubricating tube, a tubuiar body, a lid hinged thereto for movement to and from the open end thereof, a spring yieldably holding said lid in a closed position on said open end and a series of teeth projecting downwardly from the free circumferential edge of said lid for engaging an oil delivery spout, said teeth inclined in the circumferential plane of said edge, toward the hinged end of said lid.
